Low PIM

Low PIM is becoming increasingly important for both, Marco Cells installations and DAS venues. Carriers are establishing challenging PIM specifications for their DAS installations. DCC Series ™ DAS Carrier Combiners mix different high power RF carriers and attenuate them to a level that fiber systems can handle. The front end of DCC Series ™ interface trays are particularly susceptible to PIM effects. PIM at this stage can significantly diminish overall system performance. High quality DCC interfaces and components are mandatory for maximum utilization of system capacity.

At Microlab, we take quality very seriously. Of course, this includes also our market leading product lines of low PIM components. Passive intermodulation can seriously affect data bandwidth of wireless cells, and in serious cases, it can completely compromise channel functionality. Low PIM products are an essential measure to avoid this.

All our products come with excellent specifications, including PIM. So, why a LOW PIM label? The label constitutes a certificate of qualification to our customers. Only those products that offer particularly low PIM values are eligible for our LOW PIM label. The label ensures system designers, integrators and wireless operators that they will receive reliable, high quality products with outstanding PIM characteristics.

We stand behind what we say: The table below displays the PIM values we guarantee on LOW PIM labeled components and cables.
